2. CongressMatrix technology
In an ordinary conference system, the audio signals of
the microphones converge into one audio (floor)
channel which is transmitted to a PA system with only
one channel. For this reason, all system loudspeakers
get the same floor channel sound level. Differing voice
levels of orators cannot be leveled out by simply
adjusting the microphone volume. Due to feedback
from a loudspeaker influencing delegates’ nearby
microphone, a positive feedback loop is formed and
produces howl.
But due to the amassment and their close spacing
arrangement, long stem microphones greatly affect the
visual overall picture within the venue.
Therefore, in many high-level meeting rooms (e.g.
Parliament Hall), media matrices and boundary
condenser microphones are implemented to solve this
problem.
In a media matrix, the audio signal from any
microphone can be transmitted at any ratio to any
loudspeaker, thus system transmission gain can be
increased by an appropriate configuration. All
microphones are star connected. But installation,
debugging and operation are highly complex. Such a
solution should usefully only be applicable if the
microphones are within a fixed installation, controlled
by professional technical staff. Furthermore, only
discussion function is available. A media matrix
solution does not feature conference sign-in, voting,
simultaneous interpretation, video tracking and
intercom function.
To solve above-mentioned shortcomings, TAIDEN
successfully developed the proprietary
CongressMatrix
TM
technology (utility patent:
200620054419.6). HCS-8600 Series Paperless
Multimedia Congress System is the first Paperless
Multimedia Congress System in the world to integrate
an (n+8)×26 audio matrix processor (n is the number of
microphones connected in the system) in the Congress
Main Unit.
■ 26 discrete audio outputs, including:

Line 1~2 output: 31 band graphical EQ (preset
three bandwidth for fast selection: narrow band,
normal and wide band) + DRC (dynamic range
compressor) + time delay (maximum delay time is
1 s)

AES 1~2 output: 31 band graphical EQ (preset
three bandwidth for fast selection: narrow band,
normal and wide band) + DRC (dynamic range
compressor)

Group output 1~6: 15 band graphical EQ (preset
three bandwidth for fast selection: narrow band,
normal and wide band) + DRC (dynamic range
compressor) + time delay (maximum delay time is
1 s)

USB 1~2 output: 8 band parameterized EQ +
DRC (dynamic range compressor)

Dante 1~16 output: 8 band parameterized EQ +
DRC (dynamic range compressor)
■ Connectable to a multi-channel independent PA
system. Each channel is supplied with its proper
audio signal. The audio signal of each microphone
can be routed to any speaker at any ratio, thus “N-1”
function can be realized easily: when the
microphone in one area is turned on, its audio signal
is only routed to all areas except to its own, avoiding
acoustic feedback (howl) when audio transmission
gain is increased
■ 26 channels audio output function
■ Recording by group function
■ Gain and EQ (5 band) of each microphone
adjustable separately, fitting the individual orator’s
voice to achieve perfect speech pickup any time
■ Integrated high-pass filter (low-cut switch) to cut low
frequency elements from the audio when needed
■ Integrated voice enhance and howling suppression
function for each microphone to improve sound
effects
■ 2 audio line in (Line/Dante) + 2 AES in (AES/Dante)
+ 2 USB in (USB/Dante) +2 Dante in, or 1 audio line
in (Line/Dante) + 1 microphone input + 2 AES in
(AES/Dante) + 2 USB in (USB/ Dante) +2 Dante in,
gain and EQ for each input adjustable separately.
+48 V phantom power supply at microphone input,
condenser microphone can be connected directly,
maximum supports 8 Dante input.
■ Real –time display of input and output level
■ Three audio modes for selection: normal mode,
teleconferencing mode and external processor mode
■ Supports for configuration scene saving, calling and
switching
■ Connectable to multi-channel audio input or output
devices for versatile expansion of the system
